7a76a5134e Python: Add redirect modeling for Tornado 
After making https://github.com/github/codeql/pull/4995, I realized how easy
this would be :D

Will need to do some manual merge-conflict handling, but it should be all good
:)

b55817a5b2 Python: Model HTTP responses in tornado 
This is quite a simpel model, but ends up matching what we were able to do with
points-to.

I think this modeling excercise really shows that we need a bit of a different
way to model HTTP responses... but I'm not going to try to fix that in this PR.

37aa9b9d06 Python: Add prefix sanitizer on URL redirect query

d8bfa3565f Python: Simple port of URL redirect query 
Still have not added sanitizer, but seems like old sanitizer was a bit too broad
(also covering %-formatting)

1849b9e771 Python: Tornado: Handle basic route setup with tuples 
The reason this becomes valueable right now, is that we can mark routed params
as taint-sources. Longer down the line, we can (hopefully) detect that a routed
param will only accept digits, and mark it safe for some of our taint-tracking
queries.
